SPECIFICATION forming part of Letters Patent No. 623,714, dated April 25, 1899.

I Application filed October 21, 1898. Serial No. 694,201, (No model.)

To all whmn it nut/y concern:

Be it known that I, BRoR OLOF VIKTOR HELLsTRoM, engineer, a subject of the King of Sweden and Norway, residing in Norrkjoping, Sweden, have invented certain new and useful Improvements in Posts andBars Applicable for Telephone or Telegraph Posts, Railway-Sleepers, and the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying draw ings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to the manufacture of posts and bars, especially telegraph and telephone posts and railway-sleepers of beton,

with an embedded iron framingin order to obtain a complete solidity and strength of such posts or bars. These posts and bars, which become more resisting against bending and pressure than common posts of wood, have, moreover, the great advantage above wood posts that they are not affected by rot or decay. In order to prevent the action of weather on the beton, the objects may be coated with a material that is not decomposed by air and wateras, for instance, asphalt and in order to render them lighter they may either be made hollow or the stone in the beton may be replaced by a lighter material--for instance, slag.

In the accompanying drawings three different modifications of these posts, bars, and sleepers are illustrated.

Figures 1 and 2 show longitudinal sections of two differently-arranged posts. Figs. 3 and at are vertical and cross sections, on an enlarged scale, of Fig. 1; and Figs. and b are similar enlarged sections of Fig. 2.

A, Figs. 3 and 4, are four parallel solid iron bars running along the whole length of the jecting around the bars they also bind the outer layer of the beton mass, which is cast around the whole iron framing.

In Figs. 5 and 6 the bars are replaced by a single tube D, forming the core-of the post. On this tube, which eventually may be filled in the interior with cement or any other suitable matter to make the same more resistant to bending, crosses E are passed in the same way as the before-named cross-pieces B to hold the beton mass well together and to make the same resistant to bending. In order that these cross-pieces or disks may better fulfil this purpose, their outer. ends are bent upward to an angle. The bars A- (shown in Figs. 3 and 4) can of course be replaced by tubes, and similarly the tube shown in Figs. 5 and 6 can be replaced by a solid iron bar.

Figs. 7 and 8 show the invention applied especially to railway-sleepers. Figs. 9 and 10 are longitudinal and cross sections of the same on an enlarged scale. Here the round irons are replaced by shaped or angle irons F, and the bars form a square framework completely embedded in the beton mass, with the junctions x under the places where the sleepers repose. In larger sleepers two square frameworks are used, while in smaller sleepers, on the contrary, only one or, in some cases, twoframeworks of flat iron instead of shaped or angle iron. In order to keep the beton mass better together and to strengthen both square frameworks, they are provided with flat irons G, the edges of which eventually are bent to an angle.

I claim- 1. A structure made of beton or the like, having an internal metallic staying or bracing structure and anchors loosely applied thereto at suitable distances from one another and consisting of flanged plates, for the purpose set forth.

2. A structure made of beton or the like having an internal metallic staying or bracing framing comprising frame members and anchors, each of which latter consists of a flanged plate loosely applied to said frame members at suitable distances from one another, for the purpose set forth. a

3. A structure made of beton or the like having an internal metallic staying or bracing framing composed of longitudinal girths, my invention I have signed my name in presconneoting brace members secured thereto, ence of two subscribing Witnesses. and anchors, each of which latter is composed of a flanged plate loosely applied to the lon- 5 gitudinal girths at suitable distances from one \Vitnesses:

another, for the purpose set forth. CARL P. GERELL, In testimony that I claim the foregoing as TH. VAWRINSKY.
